Borderers are asked to hug trees for a minute in Peeblesshire on Sunday in a bid to take a world record for Scotland.
Dawyck Botanic Garden usually closes for the season on Saturday, but is remaining open for the tree-hugging event and entry will be free.
The garden near Stobo is one of 12 sites across Scotland – called Scotland’s Tree Trail which is being launched that day – and the simultaneous tree-hugging will take place at midday.
Dawyck’s curator Graham Stewart said: “We really need local people of all ages to come along and get involved.
“It’s free to participate, a great opportunity to be part of the launch of Scotland’s Tree Trail and we may even set a world record in the process.”
The original record for the World’s Largest Tree Hug was set by Forestry Commission England in September 2011 when 702 people hugged trees at woods in Cheshire.
The new record, set by Portland, Oregon, USA, on July 20 when 950 tree huggers gathered, is pending approval by Guinness World Records.
Scotland’s Tree Trail’s Tom Christian said: “This record attempt is a perfect opportunity to celebrate the Year of Natural Scotland, mark National Tree Week and have a bit of fun.”
He added Scotland’s Tree Trail is a collection of diverse woods demonstrating the country’s unique and global importance in arboriculture.
